AUTOMATIC RECORDING DEVICE FOR SCALES.

SPECIFICATION forming part of Letters Patent No. 669,584, dated March12, 1901.

Application iiled May 31, 1900.

To all when@ it may concern:

Beit known that I, CHESTER I. HUNT, a citizen of the United States,residing at Nunda, in the county of Livingston and State of New York,have invented certain new `and useful Improvements in AutomaticRecording Devices for Scales; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to automatic recording devices for scales.v

The object of the invention is to provide a device of this characterwhich shall be simple ot' construction, durable in use, andcomparatively inexpensive of production and which is designed to beattached to the ordinary form of spring-scales and by means of which theweight of merchandise will be recorded.

rlhe invention is particularly designed for use at dairies where it isdesired to ascertain and keepa record of the amount of milk given byeach cow.

To this end the invention consists in providing a suitable card-holderadapted to receive a card upon which is arranged vertical columnsrepresenting the dates of the month intersected by horizontal linesrepresenting units of weight, which units correspond with the graduatedface of the scale. Connected to the card-holder, adapted to moveindependently relative thereto, is a recorder, which is designed torecord the weight upon the card and, iinally,th e invention consists inproviding means for connecting the recorder to the movable part of thescales, whereby the recorder will be actuated and moved corresponding tothe movement of the movable part of said scale.

In the accompanying drawings, Figure 1 is a front elevation of anordinary springscale, showing` my invention applied thereto. Fig. 2 is aside elevation ot' the device removed from the spring-scale, and Fig. 3is a vertical sectional view through the same.

Referring to the drawings, 1 denotes an ordinary spring-scale providedwith a ring 2 for suspending it and a hook 3 for engaging with it thearticle to be weighed.

i denotes the usual indicator-point, which (No model.)

moves along the graduated face 5 of the spring-scale.

6 denotes the ca rd-holder,which is attached tothe upper end of thespring-scale in any desired manner and is provided with parallel sideflanges 7, which have longitudinal vertically-disposed slots 3, thewalls of which extend forwardly at an angle near their upper ends, asshown at tl.

10 denotes an indicator, which comprises a bail-like frame 11, the upperends ot' which are connected to a transverse shaft 12, upon which isloosely mounted the indicator-wheel 13. The ends of the shaft 12extendthrough the slots S in the side flanges of the cardholder and areprovided with heads 14. A transverse bar or shaft l5 has its endsconnected to the frame and supports an inkingroller 16, which is of lessdiameter than the indicator-wheel 13 and is constantly in contact withthe periphery of said wheel. The lower end of the bail-like frame 1l isformed wit-h a loop 17, to which is secured an indicator 1S. A set-screw19 works through this loop, and its screw-threaded end is engaged withthe indicator-point 4 of the scale.

2O denotes an indicatoren-rd, which is divided into vertical columnsrepresenting the days of the month, and these columns are intersected byhorizontal lines indicating units of weight which correspond to thoseindicated upon the face ot the spring-scale. It being desired toascertain and to record the weight of milk given by each cow, it will beunderstood that there will be a card for each cow. ln its normalposition the ends of the shaft engage the walls 9 of the slots 8 andhold the indicator-wheel a slight distance in advance of the face of thecard-holder. The card is now placed in the card-holder and a bucket orpail suspended from the hook on the scale. The weight of the bucket orpail will draw both the in dicator-points 4L and 1S downward, and thethumb-screw is loosened, so that the frame may be moved a slightdistance upward to bring the indicator-point 18 at the point marked O onthe face-plate of the scale and indicator-wheel 13 to point marked O oncard. The milk placed in said bucket will draw the frame 11 downward,thus causing the indicator-wheel to roll downward and in engagement withthe card, thus marking upon said card the n nmberof pounds of milkcontained within the pail. it is understood that the indicator-wheel 13is moved lengthwise of the shaft, so that it may be adjusted to any ofthe dated columns, so that a complete record may be kept from day to dayof the amount of milk given by each cow. Nhen the pail is removed fromthe scale, the spring of the scale will return the parts to their normalposition, with the recordingwheel out of engagement with the card, thuspermitting' the card to be withdrawn from the holder and another cardinserted preparatory to recording the weight of the milk given byanother cow.

From the foregoing description, taken in connection with theaccompanying drawings, the coi/lstruction, operation, and advantages ofmy invention will be readily understood without requiring an extendedexplanation. It will be seen that the device is exceedingl)v useful forthe purpose for which it is designed and that it may be placed upon themarket at a comparatively small cost.

Various changes in The form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what is claimed as new, anddesired to be secured by Letters Patent, is-

l. The combination with a record card holder, of a recorder movablyconnected thereto and adapted to travel over the recordca-rd and inengagement therewith, means for automatically removin the record er fromengagement with the card when the parts aro in their normal position,and means for connecting the recorder to tho movable part of aweighing-scale, substantially as set forth.

2. rlhe combination with a spring-scale, of a record-card holder securedthereto, a recorder consisting of a frame having a removable connectionwith the card-holder, a recording-wheel carried by said frame, means forautomatically removing the recordingwheel from engagement with the cardwhen the parts are in their normal position, and means for attachingsaid frame to the indicator-linger of the scale, substantially as setforth.

3. The combination with a spring-scale, of acard-holder secured thereto,a frame, a shaft connected to said lframe and having a movableconnection with said card-holder, an indicator-wheel longitudinallymovable upon said shaft, an inlring-roller carried by the frame and inengagement with the indicatorwheel, means for connecting the frame tothe indicator-finger of the scale, and means for elevating theindicator-wheel from engagement with the card when in its uppermost orelevated position, substantially as set forth.

in testimony whereof l have hereunto set my hand in presence of twosubscribing witnesses.
